In order to further expand the berthing and departure window time of 400 m container ships in Qingdao Qianwan Port area，and improve the utilization rate of berths at the wharf，this paper aims at the current demand for berthing of 400 m container ships in Qianwan Port area and high risk coefficient of the berthing and unberthing process in the restricted harbor basins. Combined with container ship mooring operation results in the harbor basins and ship maneuvering simulation test，the paper simulates the 400 m container ships in the harbor basins under different wind，current and draft conditions to carry out three typical mooring operation tests at the near-end，mid-end and far-end berths，and obtains the condom mooring conditions and ship traffic organization according to the test results. The results show that under the given condom mooring conditions and the established ship traffic organization，Qingdao Qianwan Port area can routinely carry out the mooring operation of two 400 m container ships.
